Being heavier or gaining weight does not increase the risk of hemorrhagic stroke according to data from the Nurses' Health Study.
In fact, the opposite was true. The risk of hemorrhagic stroke was greater in lean women compared to heavier women, although the difference was not statistically significant.
(There was a 20% chance that this was due to random chance, and an 80% chance this was due to difference in weight. To be statistically significant, there has to be less than a 5% chance that the difference is due to random chance.) Subjects
